IMPROVEMENT IN CONDUCTORS PUNCHES.

Specification forming part of Letters Patent No. 162,071, dated April 13, 1875 application filed January 8, 1875.

To all whom it may concern:

Be it known that I, OLIVER T. HUNGER- FORD, of New Hartford, in the county of Litchfield and State of Connecticut, have invented a Conductors Punch, of which the following is a specification, reference being had to the accompanying drawings, where Figure l is a side view of the same. Fig. 2 is a similar side view with the covering-plate removed, so as to show the interior construction. Fig. 3 is a top view of the punch. Fig. 4 is a similar top view with a part broken away. Fig. 5 is a bottom view. Fig. 6 is a detail side view of a modification of the anvillever. Fig. 7 is a detail top view of a modification of the anvil-lever.

The device is a punch for the use of railwayconductors and others who have need of simi lar punches.

The body of the punch is composed of two partsthe case a, which mainly contains the operating mechanism, and the punch-base a. Underneath the body is the ring a These three parts, a, a a are, by preference, made all in one piece of malleable cast-iron or dropped wrought-iron. The ring a is intended to slip upon the forefinger of a persons hand, leaving the anvil-base a pointing outward and the case a pointing inward. The ring is thus placed, in a certain though not strict sense, centerwise of the body, enabling me to shorten the body of the device and hang the pivot of the punch-lever nearly over the forefinger. The case a has a cover or side cap, 11, secured to the case by screws 0 and d. On the screw 0 is hung the punchlever 6, running through a mortise in the tail of the thumb-lever f, and borne down upon, so as to keep the punch-jaws open, by the spring g. Onthescrew d is hung the thumb-lever f.

When the device is held on apersons forefinger the lever is in good position to be pressed down upon by the persons thumb, and this action causes the jaw of the punchlever to close upon the punch-base a This punch-base a bears the punch i, which projects into the corresponding punch-seat in the jaw of the thumb-lever when the two jaws come together, and, a card or ticket being held in the path. of the punch at such time, a hole is punched in the ticket.

The letter m denotes a rubber cushion, and n a spring overlying this cushion.

In the modification shown in Figs. 6 and 7 the cushion and spring 112 n are dispensed with, and a slit, 0, is shown in the jaw of the punch-lever for the insertion of the ticket to be punched.

With reference to the second clause of the following claim I have to say that I do not intend to cover and claim all combinations of two levers with a punch-base, but only a combination where the construction and arrange ment are such that the power end of the thumb-lever overhangs the punch-base, and in the act of punching is moved toward the punch-base, and by the same movement moves the punch-bearing end of the punch-lever toward the punch-base, such an arrangement of the two levers being essential to attain the compactness, and at the same time retain the power, of my device.

I claim as my invention 1. In an apparatus for punching tickets, cards, 850., the body or case a, of one piece, provided with a punch-base, a and ring a set underneath and centrally of the body, all substantially as and for the purpose described.

2. The combination of the thumb-leverf, its power end overhanging the punch-base, the punch-lever e, and the punch-base a all substantially as set forth and described.

3. The combination of the body a, provided with the punch-base a and ring a", set centrally underneath the side cap I), and the levers e f, all constructed and arranged substantially as and for the purpose described.

OLIVER T. HUNGERFORD.
